HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

3-Bromo-4-methoxypyridine is a heterocyclic building block featuring a bromine at the 3-position and a methoxy group at the 4-position on the pyridine ring. This combination imparts enhanced reactivity in cross-coupling processes while maintaining stability under standard conditions. The electron-rich aromatic core facilitates palladium-catalyzed transformations, enabling efficient integration into pharmaceutical intermediates and functional materials.

Application

3-Bromo-4-methoxypyridine serves as a versatile building block in medicinal chemistry, enabling palladium-catalyzed cross-coupling reactions such as Suzuki-Miyaura and Stille couplings. The bromine substituent provides high reactivity under standard conditions, while the methoxy group enhances solubility and offers orthogonal functionalization potential. This compound exhibits excellent bench stability and is readily purified by flash chromatography, making it ideal for iterative synthesis of heterocyclic scaffolds and API intermediates.
